Hey, I am looking at a 1977 f-250 with a 351M, C6, on propane which i think I could get for $1500-$1900. It has a nice set of wheels on it (probably worth $400-$800) and had a paint job done a couple of years ago it also has some rust. I also have a 1978 F250 with a 400 4 speed with some rust. I recently got a couple of quotes on the body work. I was told $1100 dollars (canadian) by one guy for just sort of fixing it so it looks good and anywhere between $5000 to $10000 for a proper restore buy a guy that does a really good job. The reason i am writing this is i am looking at blending the two trucks together. I am looking at taking the propane frome the 77 and the engine (if it was built for propane) and putting them on my other truck. I have 2 400's the one in the 78 has bearing problems from a rebuild. The other one has a RV cam and was possibly rebuilt but i do not no the specs. Around here propane is 60 cents a litre versus 114.9 for gas. That is my reasoning for the propane from the other truck (which i am currently pursuing details on like the age of the tanks. I am just looking for some feedback on these ideas and would like to here about other peoples experience with propane and blending 2 trucks.

Thanks

 

Just keep in mind that you don't get the same distance per litre on propane, due to the lower heat content. So you won't be quite as far ahead as it seems.

Also, maybe it's just me, but I find propane trucks very unsatisfying to drive.

Probably will be slightly cheaper in the long run though, depending on how far you drive.

 

Yah i've heard that if you tune the engine right it will get equivalent mileage and when i could pick up another system for 500 buck or less i starts too seem more worth it
i am not worried about powerloss so i'll have to see

 

Check with the alternative fuels forum for propane info. Propane will not get the same mileage even "tuned up right".

As far as blending the two trucks with the "donor" vehicles in hand you should not have too much trouble. Be prepared for some fabrication tho. Hopefully you have the required experience with mechanical and electrical skills.

 

it is true that they wont get the same milage but they can produce some very good performance if the engine is set up for it.Now for the age of the tanks there will be a tag welded to the tanks it has the asme rating and the year they were built the working pressure and the water capacity also it should have a stamed u69 inside a small box.used to be a service tech for a propane company and all are trucks ran on propane also converted lots of truck and cars make them breath and the correct cam and thy will go like hell!!
